Architecture Differences

The Intel Core i3-1315U and AMD Ryzen 3 7320C represent two different approaches to mobile processor design. The Intel part is built on the Raptor Lake architecture, using a 10nm process at Intel's foundry. It is a hybrid design with 6 cores (2 Performance and 4 Efficient cores) and 8 threads, allowing the operating system to schedule workloads across a mix of high-performance and high-efficiency cores. The AMD Ryzen 3 7320C, in contrast, uses TSMC's 6nm process and the Zen 2 microarchitecture. It is a more symmetrical design, with 4 full Zen 2 cores and 8 threads.

Cache allocations differ. The Intel chip has a hierarchy with 80 KB of L1 cache per core, 1.25 MB of L2 per core, and a shared 10 MB L3. The AMD part has a smaller per-core cache: 64 KB L1 and 512 KB L2, and a shared 4 MB L3.

Memory and I/O also diverge significantly. Intel supports both DDR4 and DDR5, while AMD is limited to LPDDR5. Both processors support dual-channel memory. The Intel chip uses a newer PCIe Gen 4 interface with 8 lanes, while the AMD chip uses Gen 3 with 4 lanes. Integrated graphics solutions are present on both chips: Intel's UHD Graphics 64EU and AMD's Radeon 610M.

Head-to-Head Benchmarks

The benchmark data shows a clear pattern of Intel dominance in compute-heavy workloads. In the Cinebench R23 multi-core test, the Intel Core i3-1315U scored 9374, which is 33.4% higher than the AMD Ryzen 3 7320C's 7025. The single-core advantage is similar: 1323 versus 991, a 33.5% lead. These margins hold across the Cinebench R20 and R15 tests as well. The Intel chip scores 3937 in Cinebench R20 multi-core (33.5% ahead of the Ryzen's 2950) and 133 in Cinebench R15 multi-core versus 708 (33.3%).

In Cinebench R23 single-core, the Intel chip leads again: 1323 versus 991, a 33.5% difference. In Cinebench R20 single-core, it is 555 versus 416 (33.4% faster). In Cinebench R15 single-core, Intel scores 133 versus 99, a 34.3% lead. This consistent 33%+ lead in all Cinebench variants suggests that the Intel core's higher IPC and clock speeds provide a significant advantage in both lightly threaded and heavily threaded rendering workloads.

The AMD Ryzen 3 7320C, however, has a strong advantage in data compression. In Passmark's data compression test, the AMD chip scored 144,465 against the Intel's 126,436, a 12.5% win. In random string sorting, AMD also leads: 16,973 against 14,028, a 17.4% advantage. These are memory-latency and memory-bandwidth sensitive tasks, where the AMD platform's memory subsystem appears more efficient.

The Intel chip dominates in most other Passmark workloads. In data encryption, Intel wins: 7,583 versus 5,443, a 39.3% delta. In extended instructions, Intel's lead is even larger: 7,413 versus 3,663, a 102.4% advantage. Prime number search shows a massive 127.8% lead (41 versus 18). Floating point math shows 92% (27,012 versus 14,071). Integer math shows a 16.7% lead: 37,644 versus 32,247. In multithreaded tasks, Intel's lead is 38.9%: 11,482 versus 8,265. In physics, Intel leads 41.2%, 706 versus 500. Single-thread PassMark is also Intel, 3,380 versus 2,439, a 38.6% lead.

Overall, the Intel Core i3-1315U wins 15 of the 17 benchmark comparisons, while the AMD Ryzen 3 7320C wins 2.

Where Each One Wins

The Intel Core i3-1315U is the stronger general-purpose processor. Its 33% to 34% lead across the Cinebench suite makes it a better choice for anyone running multi-threaded productivity workloads, 3D rendering, video encoding, or other applications that rely on sustained multi-core performance. The consistent single-core lead, also in the 33% range, makes it the better option for lightly threaded, latency-sensitive workloads as well. The 38.9% win in PassMark multithreading and the 38.6% lead in single-threaded tests underline its superiority in everyday multitasking and general responsiveness.

The AMD Ryzen 3 7320C, however, is not without merit. Its wins in data compression (12.5%) and random string sorting (17.4%) show that in memory-bandwidth-heavy tasks, it can outperform the Intel competitor. This makes it a viable option for workloads such as database operations, data analytics, or any workload that is primarily memory-bandwidth bound rather than core-bound.

For most users, the Intel Core i3-1315U is the recommended choice. Its consistent lead across all Cinebench variants and the majority of PassMark tasks gives it a broader performance envelope. In scenarios where memory bandwidth is the primary bottleneck, the Ryzen chip's wins should be considered. The data indicates that the Intel processor is the higher performing chip for the vast majority of workloads.
